An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

[jedimstr]

Hello, I try to use mining_proxy.exe with Minerd

Code:

mining_proxy.exe -pa scrypt -o stratum-us.doge.hashfaster.com -p 3339

Code:

minerd.exe -a scrypt -o stratum+tcp://ltc.ouranos.fr:3333 -u myworker_1 -p mypass_1 -o stratum+tcp://127.0.0.1:3333 -u myworker_2 -p mypass_2

When I use these two lines,
there is the last pool that works. (the one that goes through the proxy)

If I cut the proxy or the pool behind the proxy is no longer accessible. I thought he would switch to the first pool.

But he refuses

Where is the error in my command linne?

thanks

Unlike BFGMiner or CGMiner, minerd/CPUMiner does not support multiple or failover pools.  Only the last pool parameters will be recognized.

The win64 binaries for 2.3.3 report a BitcoinMiner trojan in many antivirus softwares:

False positives or a very bad situation?

BTW The scan is done on the original sourceforge link.

Well, it is a miner program...

Antiviruses tend to report all of them as viruses because there are trojans out there which hijack computers to use them for mining unbeknownst of their owners.

Hello, I'm using cpuminer to do some Litecoin mining using https://give-me-coins.com. The OS is Windows 7 x64.

Version 2.3.2 works fine; version 2.3.3 instead just keeps saying "...retry after 30 seconds", as if the pool server was unavailable (which is not the case).

The launch command is exactly the same for both versions:

Code:

minerd.exe -o stratum+tcp://ltc-eu.give-me-coins.com:3333 -O Username:Password

What's wrong here?

I can reproduce this (even if not consistently) on Linux under Wine using both the 32-bit and the 64-bit Windows binary. The issue disappears, however, if I replace the libcurl DLL provided with cpuminer 2.3.3 (libcurl 7.35.0) with the older libcurl DLL from cpuminer 2.3.2. After further testing, I was able to reproduce the issue with libcurl 7.35.0 and 7.36.0, but not with 7.34.0 or 7.33.0.

The problem keeps randomly happening.

Once it connects I can mine without problems for hours, but sometimes it simply doesn't connect and just gives the "...retry after 30 seconds" message. As before, 2.3.2 Always works; only 2.3.3 exhibits this behaviour.

Have you tried replacing the libcurl DLL with the one that came with cpuminer 2.3.2 (rename it as needed)?

This works. The problem really seems to be caused by libcurl.

Your syntax is incorrect.
Your miner/s is/are not communicating with the pool hence "retry after 30 seconds" due to this.
It should look something more like this:

minerd --freq=850 --gc3355=comX --url=stratum+tcp://ltc-eu.give-me-coins.com:3333 --userpass=xxxx.x:xxxx

also, try minerd --help for help

Good luck!

My syntax is perfectly correct, please have a look at the README again.

2.3.2 always works, 2.3.3 works sometimes but not always; if the syntax was indeed incorrect, it would never work.

Massimo80's syntax is correct. wolfey2014's suggestion, on the other hand, includes inexistent parameters, which may apply to some ASIC fork of cpuminer, but not to the original software discussed in the present thread.

Sorry, I'm using ver for GC3355.... thought you were too. Just woke up when I first tried to help you.
Guess I should wait until I've had my coffee 
Best of luck!

Help, I do want to try this mining using my lappy, however when I open the .exe file it just pop-up then gone,
I downloaded the 64bit since I have a 64bit version of windows.
Is there any step by step tutorial how to set this in a windows?please teach me how..

Google "batch file for *insert miner name here* + optionally your hardware". But there isint much out there you could profit from with mining with your laptop CPU, so check your profitability before mining.

Some mobile laptop gpus can be profitable but that is assuming your lappy has one in the first place.

[gentacomp]

Any readme file ?
Description code for -t or -q etc... ?

Thank you

This isn't the right place to ask for support for a cpuminer fork, you should PM me directly (include the full log contents).

Good day.

using cpuming,
minerd.exe --url=stratum+tcp://stratum.btcguild.com:3333 --userpass=user:pass

results issued by the program below, the site btcguild.com dashboard also shows zero results.

where is the problem? (speed of the system and other related problems now are not interesting now, I want to understand the work prinitsipe)

You need to use the SHA-256d algorithm for Bitcoin mining. Add --algo=sha256d to your options.

I just did a full re-install of my OS and noticed a new version of CPU miner was out (Before I was on 2.3, first one with stratum built in).   Anyway, I've installed the new version and while it works, with the same hash rates as before, I'm noticing I'm getting a ton of "accepted xx/xx (%) (booooo) compared to the older version.   Has something changed in newer versions?  If I stick my old boot hard drive into the machine the 2.3 version of CPU miner on it, it works on the same pools with nearly 100% accepted rate.   With this new version I'm getting accepted rates around 60-70%.

MacOS 10.9.2 (Clean install) and the latest version of CPU miner..    Can someone possibly walk me through how to uninstall this most recent version and the re-install using the older version? (I still have the older version in a folder backed up).



/edit  I successfully downgraded to version 2.3.2 and am back to seeing normal accepted rates.  I wonder what it is about 2.3.3 that causes so many "boooo" submissions?

Weird. It would be nice if you could try all versions from 2.3 to 2.3.3 (they are all available at SourceForge) and see which of them seem not to work. Also, please post (or send me via pm) the exact command-line options you are using so that I can test if there's a problem with the server you are connecting to.

Originally I was on 2.3 as I mentioned in the post, and now I am on 2.3.2 and it's working fine.  When I rm minerd from the usr/bin/minerd and replace it with the 2.3.3 version I get much lower.... well, it still says accepted but says "boo" and the percentage drops.

2.3.2 seems to work fine with near 100% accepted over several hours.

This was tested over the last 2 days on both give me coins and clevermining.

Launch strings are:
minerd --url stratum+tcp://us.clevermining.com:3333 --userpass <my address>:x -t 24
and
minerd --url stratum+tcp://ltc.give-me-coins.com:3334 --userpass <my worker>:x -t 24

I tried less threads to see if that helped and it made no difference.     This is a 2012 MacPro upgraded with dual 6 core 3.46 Xeon 5690's.  32GB RAM.  Fresh install of OSX 10.9.2.  The same result happened when tested on my older 2008 3.2Ghz 8 core MacPro. with 10.9.3 (Appleseed Beta release).
